We introduce a very interesting software RAM disk, it can turn memory into a hard disk to use, is always relatively advanced use methods. Of course, the capacity of the hard disk is much larger than memory, why should the memory when the hard disk use it?
This is because the memory read and write speed, is hard drive read and write speed of more than 10 times times. If we set the browser's cache Temp folder to memory, it can effectively improve the b

RamThe RAM is a X 8 static TTL RAM. We can program the RAM by means of the address and data switch registers. This allows us to store a program and data in the memory before a computer run.During a computer run, the RAM receive 4-bit addresses from MAR and a read operation is performed. The instuction or data word stor
Random access memory (RAM) is the equivalent of a mobile store on a PC, used to store and save data, and can be read and written at all times.
RAM is typically used as a temporary storage medium (which can be called system memory) for an operating system or other running program. However, when the power is off, RAM cannot keep the data, and if the data needs to

Summary of the basic features of the Random access memory:① Random Access The so-called "random access" means that when a message in memory is read or written, the time required is independent of where the piece of information resides. In contrast, when reading or writing sequential access (sequential access) to the information in a storage device, it takes time and location to have a relationship (such as tape). ② volatile RAM cannot retain data w
